Three people left 3 different trails. We give you here the start and the ends of each one of the people (you don’t know who ended where). We also give you how many times each one of the people has turned up, down, right or left and how many times each one of the people get into an intersection that someone else has also passed. A: north 5, south 1, east 3, west 2, crosses 9
B: north 5, south 0, east 2, west 2, crosses 8
C: north 6, south 1, east 2, west 4, crosses 9

Can you reconstruct the three trails?

No one crosses their own path.
